A New York Times article reported that a survey conducted in 2014 included 36,000 adults, with 3.72% of them being regular users of e-cigarettes. Because e-cigarette use is relatively new, there is a need to obtain today's usage rate. How many adults must be surveyed now if a confidence level of 95% and a margin of error of 1 percentage point are wanted? Complete parts (a) through (c) below.
